Jake Gyllenhaal was most recently seen on cinema screens as a creepy video journalist in Nightcrawler, a role for which he lost more than two stone.
When audiences next see him, however, he will be almost unrecognisable as a middleweight boxer in Southpaw.
We literally turned him into a beast. Jake, my God, he's a very electric, powerful fighter in this movie. He's so committed and gives his heart. The word is sacrifice.
- Southpaw director Antoine Fuqua, speaking to Deadline Hollywood
